The Crickit can drive up to four standard (also called hobby) servo motors via the Servo connections block.
The four servo block is identical on the Crickit for Circuit Playground Express, Crickit Wing for Feather, and Crickit for micro:bit.
You can connect up to 4 servos.
Your servo will have a 3-pin connector with black or brown, red and white or yellow wires.
Connect the servo to the 3 pins next the number 1. The light colored wire should be pointing out and is closest to the number '1' marked on the Crickit, the darkest color wire pointing towards the center of Crickit.
Make sure it presses down and looks like all three wires of the servo are attached to Crickit.
Please see the following pages on how to program servos on Crickit in either Microsoft MakeCode or CircuitPython.
